SELF LUBRICATlNG WHEEL.

\ SPECIFICATION forming part of Letters Patent No. 300,913, dated June 24-, 1884-. 5

Application filed May 16, 1884. (No model.)

I0 a, w/wm. it may concern:

Be it known that I, WILLIAM T. SNYDER, a citizen of the United States, residing at Oatasauqua, in the county of Lehigh and State of Pennsylvania, have invented anew and useful Improvement in Self-Lubricating Wheels, of which the following is a specification.

My invention relates to wheels that work loose on an axle or shaft; and the object of my improvement is the construction of a loose wheel with a reservoir or oil-chamber in the hub, that will effectually lubricate the axle or shaft.

The invention consists in the combination, with the hub, of a loose wheel, an oil or grease chamber of irregular shape, and open to the axle or shaft by a slot diagonal to the hole of the wheel or axle or shaft, as will be hereinafter shown and described, referring to the annexed drawings, making a part of this specification, in which- Figure 1 is a front or face View of a wheel having a hub constructed according to my im provement. Fig. 2 is an edge view. Fig. 3 is a vertical section on a line of XX, Fig. 2. Fig. 4 is a vertical section on a line of X Y, Fig. 1.

Similar letters refer to similar parts throughout the several views.

The construction of my improved self-lubricating wheel is as follows: The hub A is constructed somewhat larger than usual. In this hub I cast a chamber, B, (shown by the dotted-lines in Fig. 2,) in the form of a figure 8.

In section,Fig. 4.,it is shown in form of the let- 3 ter S. This chamber opens into the hole of the wheel by a slot,D,of a form as is shown in Fig. 4, which is a diagonal curved opening across the face of the hole. The chamber B is constructed with break-walls G G. His an opening in the hub for charging the chamber B with oil. This opening should be stopped with a screw-plug. to exclude dirt.

- Theoperation of my improvement is as follows: Oil is .placed in the chamber B. WVhen the wheel revolves,it will give a motionto the oil, throwing it from the center. The oil will come in contact with the break-walls G G, which will break the flow of oil and force it against the axles or shaft, thereby keeping the same lubricated under all speeds.

I claim- In a wheel with a cast hub, A, for working loose on its axle or shaft, the combination of an oil or grease chamber, B, of irregular shape, with the diagonal opening D and breakwalls ,G G, as shown, described, and for the purpose specified.
